Heptalene is a non-planar bicyclic 12 pi electron system. It has two dynamic processes, Double Bond Shift (DBS) and Double Ring Inversion (DRI), which lead to four interconnective isodynamic structures. The non-planarity of the two rings in heptalene is responsible for their inherent chirality and stimulates the experimental investigation of the question whether the heptalene backbone would be useful as a template for bidentate ligands for homogeneous transition-metal catalysis. In this book, we aimed first at synthesis of diphenylheptalene derivatives, taking the corresponding azulenes as the...
